Core Data File Sharing via an AFP Alias


  • Subject: Core Data File Sharing via an AFP Alias

Hello,

Despite warnings on this list about data corruption, I want to experiment with sharing a Core Data SQLite database over AFP.  However, I can't seem to get to first base.

My Core Data app is running on two computers.  One one, the app accesses the database file directly on its internal hard drive.  On the second computer, the app accesses the database via an alias to the remote file over AFP.  As soon as the second (remote) computer connects to the database (via the alias), the main computer is unable to save to the database, giving 'Cocoa Error 134090'.  (That error number doesn't appear in the versions I have of the error header files.)

As an experiment, while in that un-savable state, I opened the database file in BBEdit, changed a character and saved it to verify that the file wasn't locked or busy or...  It saved without issue.

Can anyone suggest a method of sharing the database file in that manner?

Thanks,

Steve
